Using Mangago

Eh skrew romance
What’s your favorite friendship or friend group dynamic you’ve seen in anime/manga/webcomics?
Platonic relationships are da bomb.
Especially dat enemies to friends, immaculate
Also family too, but not in an insest way, insest is disgusting. What I’m talking about is characters looking out for their siblings and parents/guardians being protective of their children. It warms ma heart ٩(๑❛ᴗ❛๑)۶
